[0001] The present invention belongs to the technical field of nut production, and specifically relates to a positioning and grinding device for the production of building support nuts. Background Art

[0002] Building support nuts (such as scaffolding connection nuts, anchor bolt nuts, etc.) usually require high-precision processing to ensure thread fit and load-bearing strength. In the production process of building support nuts, the grinding process is a key link to ensure the surface finish, thread accuracy, and deburring of the nuts;

[0003] For example, the utility model with the publication number CN221716485U discloses a positioning and grinding device for nut production, including a bottom plate. A first motor is fixedly arranged at the top end of the bottom plate, a turntable is fixedly arranged at the output end of the first motor, several placement grooves are formed in the turntable, a through hole is formed at the center position inside the placement groove, a column is fixedly arranged at the top end of the bottom plate, and a support plate is fixedly arranged on the outer side of the column. In this utility model, the nut is placed inside the placement groove, then the first motor is started, and the first motor drives the turntable to rotate, so that the nut placed inside the placement groove moves along with it until the nut moves to the grinding mechanism and the fixing mechanism. The fixing mechanism fixes the nut, and then the grinding mechanism grinds. After grinding is completed, the fixing mechanism releases, and the first motor starts to drive the turntable to continue moving until the next nut is ground. Then, the ground nut is taken out, and a nut to be ground is placed. In this way, the continuity of the grinding work is ensured.

[0004] Most of the existing grinding devices are in an open grinding state, and a large amount of metal dust and abrasive particles will be generated during the grinding process, which not only pollutes the working environment, but also seriously affects the health of operators and the service life of equipment. Traditional grinding measures usually rely on operators wearing protective equipment, such as protective masks, protective gloves, and protective clothing, etc. However, these measures often cannot comprehensively and effectively protect operators from various hazards of dust; at the same time, the lack of protective performance of the existing devices may cause dust to enter precision components such as guide rails and motors, accelerating mechanical wear and reducing the service life of the machine.

The driving disk is rotatably connected to the top of the fixing disk.

[0016] Preferably, a plurality of moving grooves arranged in a circular array are provided on the fixing disk, the plurality of moving grooves are in a cross shape, and the cross section of the moving groove is in a T shape.

[0017] Preferably, a plurality of the movable rods are slidably arranged inside the moving grooves.

Through the driving assembly, the motor drives the driving disk to rotate. By using the cooperation of the arc-shaped groove on the disk surface and the limiting rod, the movable rod is pushed to slide along the moving groove. When the limiting rod moves to the outer end of the arc-shaped groove, the movable rod expands outward to expand the range of the protective cover, and the sealing film stretches. When it moves to the inner end of the arc-shaped groove, the movable rod retracts inward to narrow the range of the protective cover, and the sealing film contracts, realizing flexible adjustment of the protection range.

[0023] Through the cooperation of structures such as the air blowing pipes, the air pump, and the collection box, the present invention facilitates the unified collection of the polishing dust. Through the guiding assembly, the air pump blows air into the protective cover, concentrating the dust generated during polishing and blowing it towards the slot opening at the top of the base, and finally falling into the pull-out collection box for unified treatment, realizing efficient dust removal and convenient cleaning.

[0033] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0034] As Figures 1 to 8 shown, the present invention provides a positioning and grinding device for the production of building support nuts, including a base 1. The base 1 is in a hollow state, and a plurality of notches are opened at the center of the top. The plurality of notches are circular in shape, and a connecting seat 11 is fixedly arranged on the top of the base 1;

[0035] a grinding head 2, which is located at the bottom of the connecting seat 11 and directly above the notch, and is used for grinding the nut. An electric push rod 21 is fixedly arranged on the top of the grinding head 2;

[0036] The dust-proof mechanism 3 is arranged at the bottom of the connecting seat 11 and on top of the electric push rod 21. The dust-proof mechanism 3 is used to prevent dust and debris generated during grinding from spreading.

[0037] Among them, the dust-proof mechanism 3 includes a plurality of protective covers 31, a sealing film 32 fixedly arranged at the connection of the plurality of protective covers 31, a driving component 33 located at the top of the protective cover 31, and a guiding component 34 arranged inside the protective cover 31. The plurality of protective covers 31 are arranged in a circular array. The plurality of protective covers 31 are all in an irregular arc shape and gradually become larger from top to bottom. The sealing film 32 is an LLDPE stretched film, which has strong stretchability and resilience, and can ensure that when adjusting the plurality of protective covers 31, the connection of the protective covers 31 remains in a sealed state to prevent dust from splashing out.

[0038] With the above scheme: When the grinding device works, first place the nut to be processed stably on the base 1. Subsequently, through the linkage of the connecting seat 11 and the electric push rod 21, drive the grinding head 2 to move down precisely to perform efficient and stable grinding processing on the nut. To effectively control the metal dust generated during the grinding process and ensure the cleanliness of the operation environment and the visual monitoring of the processing process, the device is equipped with an intelligent dust-proof mechanism 3. This mechanism adopts a modular design. The driving component 33 automatically adjusts the positions of the plurality of protective covers 31, enabling it to flexibly adjust the dust-proof range according to the size of the nut to be processed, thereby adapting to workpieces of different specifications and improving the versatility and adaptability of the equipment. During the process of adjusting the dust-proof range, the flexible sealing film 32 stretches or resets synchronously with the expansion and contraction of the protective cover 31, always maintaining a sealed state, effectively preventing dust from overflowing. In addition, the device is also integrated with a set of efficient guiding components 34, which can actively guide the dust flow to a specific collection area during the grinding process, facilitating subsequent centralized cleaning, ensuring a clean working environment, and at the same time reducing the impact of metal debris on the processing accuracy.

[0039] As Figure 6 shown, the driving component 33 is located at the center of the bottom of the connecting seat 11. The driving component 33 is used to quickly adjust the protection range of the plurality of protective covers 31. The driving component 33 includes a fixing frame 331, an electric cylinder 3311 fixedly arranged on the top of the fixing frame 331 and fixedly connected to the connecting seat 11, a driving disk 332 located at the center of the inside of the fixing frame 331, a gear 333 arranged on one side of the driving disk 332, a motor 334 fixedly installed on the top of the fixing frame 331 for driving the gear 333, a fixing disk 335 fixedly installed at the bottom of the fixing frame 331, and a plurality of moving rods 336 arranged in an annular array and slidably arranged inside the fixing disk 335;

[0040] The driving disk 332 is disc-shaped, and a plurality of teeth meshing with the gear 333 are provided at the edge. A plurality of arc-shaped grooves distributed in an annular array are formed on the surface of the driving disk 332. The driving disk 332 is rotatably connected to the top of the fixed disk 335. A plurality of moving grooves distributed in an annular array are formed on the fixed disk 335. The plurality of moving grooves are cross-shaped, and the cross-section of each moving groove is T-shaped. A plurality of moving rods 336 are slidably arranged inside the moving grooves. Connecting blocks 3361 are fixedly arranged at one ends of the plurality of moving rods 336 away from each other. The plurality of connecting blocks 3361 are fixedly connected to the plurality of fixing frames 331. Limiting rods 3362 are fixedly arranged at one ends of the plurality of moving rods 336 close to each other. The limiting rods 3362 are clamped inside the arc-shaped grooves and are limited by the moving grooves.

[0041] Adopting the above solution: The position of the protective cover 31 is reasonably adjusted through the driving assembly 33. The driving disk 332 is driven to rotate synchronously by the rotation of the motor 334. Since a plurality of arc-shaped grooves are formed on the surface of the driving disk 332, the limiting rod 3362 clamped inside the arc-shaped groove will be driven to displace synchronously during the rotation of the driving disk 332. Due to the limiting effect of the moving groove on the limiting rod 3362, it will slide along the moving groove, and then the entire moving rod 336 will slide along the moving groove. When the limiting rod 3362 rotates to the outermost end of the arc groove, the moving rod 336 moves outward and expands, thereby driving the expansion of the protection range of the entire protective cover 31. During this process, the sealing film 32 is in a stretched state. When the limiting rod 3362 is clamped with the side of the arc-shaped groove close to the arc, at this time, the moving rod 336 approaches the center of the fixed disk 335, driving the connecting block 3361 and the protective cover 31 to approach each other, thereby reducing the protection range. During this process, the sealing film 32 is in a contracted state.

[0042] As Figure 4 shown, the guiding assembly 34 is used to blow the dust inside the protective cover 31 into the slot opening. The guiding assembly 34 includes a blowing air pipe 341 fixedly arranged on a plurality of protective covers 31 and an air pump 342 fixedly arranged on the protective cover 31 for driving the blowing air pipe 341 to blow air;

[0043] A fixture 4 is arranged at the center of the top of the base 1. The fixture 4 is used to fix the nut to be polished. A collecting box 5 is slidably arranged inside the base 1. The collecting box 5 is used to collect the dust generated during polishing.

[0044] Adopting the above solution: The guiding component 34 of the device adopts an intelligent dust removal design. During the grinding operation, a directional air flow is generated by a high-performance air pump 342, and a ring-shaped air curtain is formed in cooperation with a specially designed sealing film 32. This air curtain system can efficiently converge the grinding dust in all corners inside the protective cover 31 to the central area, forming a concentrated dust flow. Under the guiding action of the air flow, all suspended dust is precisely guided to a carefully designed annular dust collection notch at the top of the base 1. This notch adopts a tapered structure design, which can effectively prevent dust rebound and ensure the dust collection efficiency. The collected dust naturally settles to the detachable collection box 5 at the bottom through the built-in diversion channel. The collection box 5 adopts a drawer-type installation structure, equipped with a leak-proof sealing strip and a convenient handle. After the operation is completed, the operator only needs to gently pull the handle to smoothly pull out the collection box 5 along the precision guide rail, realizing the safe transfer and centralized treatment of the dust.

[0045] The working principle and usage process of the present invention: When using this grinding device, the operator first needs to firmly clamp and fix the nut to be processed on the base 1 through a precisely designed fixture 4. To ensure the processing accuracy, the device adopts a cooperative working mode of an electric push rod 21 and an electric cylinder 3311 to precisely control the vertical downward movement of the fixing frame 331 and the grinding head 2. When the bottom of the protective cover 31 is completely attached to the surface of the base 1, the entire processing area is completely enclosed, forming a sealed dust-proof space. The protective cover 31 is carefully made of high-transparency acrylic material, which not only has excellent impact resistance but also allows the operator to clearly observe the grinding process throughout. This design not only ensures the precise control of the processing quality but also ensures the safety and visibility of the operation process. To adapt to the processing requirements of nuts of different specifications, the device is equipped with an intelligent dust-proof range adjustment system. Through the meshing transmission of a precision gear 333 and a driving disk 332, multiple moving rods 336 can be synchronously controlled to move radially along the guiding track of the fixed disk 335, thereby realizing the intelligent adjustment of the dust-proof range of the protective cover 31. In terms of the dust removal system, the device integrates an efficient air flow dust removal solution. After starting the air pump 342, the high-pressure air flow forms a directional air flow through a special air blowing pipe 341, blowing all the metal dust generated during the processing into a special notch, and these dusts will eventually be collected in the large collection box 5 at the bottom, realizing the unified recovery and treatment of the dust. The entire dust removal process is efficient and environmentally friendly, fully meeting the environmental protection standards of modern industrial production.
